[FIXED] How to reverse the slope of a graphed line

Issue

I'm trying to make a simple budget line graph that you would see in an economics class. But I need the slope of my line to be from 60 to 15 (inverse of what it is now).

I tried inversing the axis using numpy.flip() and plt.gca().invert_xaxis()

But I want to keep the x & y axis the same, just reverse the slope of the line so it shows from 60 too 15. I'm new to python and any help would be appreciated. I have included an image of my code below.

Solution

I think this is what you're looking for

plt.plot(x_[::-1], y)

The operation being done here reverses the order of the elements in the 'x_' array, resulting in the inverse of your slope.
